I need help in installing python development packages (python27-devel) on Centos5.8. Upgrading hardware is not an option as of now.

I've installed python2.7 in the same machine by

$ wget --no-check-certificate http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

$ ./configure --prefix=/usr/local/Python2.7

$ make altinstall

Now I need help in installing python-devel package for 2.7. 

$ sudo yum info python2.7-devel gives no info. Whereas the package is there for python26-devel.

Tried many suggestions after googling but still no luck. Any help or pointer for exact steps will be great. 

Thanks
